REPLACEMENT PARTS
The emission control systems on your engine were designed, built and
certified to conform to Canadian emission regulations. The use of genuine
parts is recommended whenever maintenance is done to the engine. Genuine
replacement parts are manufactured to the same standards as the original
parts. Using replacement parts that are not of the original design and quality
may impair the effectiveness of your emission control system.
It is the responsibility of the manufacturer of an aftermarket part to certify that use of
the part will not result in a failure of the engine to comply with emission regulations.
SERVICE THE AIR FILTER
NOTICE! Operating the engine with a damaged or missing air filter will
allow dust and debris to enter the engine, causing rapid engine wear or
scoring on the engine pistons. Always ensure the air filter is in place.
A dirty air filter will restrict airflow to the carburetor, reducing engine
performance. If the engine is used in very dusty areas, clean the air
filter more frequently than specified in the maintenance schedule.
1.
Remove the air cleaner's outside cover. Be careful to prevent
dirt and debris from falling into the air cleaner assembly.
2.
Remove the air filter from the air filter housing.
3.
Clean the housing interior with warm soap and water.
Allow to dry before reassembly.
4.
Inspect the air filter to see if you can clean it or if it should be
discarded. Discard if it is too dirty and replace with a new filter.
a.
Clean dirty air filter with warm water and mild soap or a non-
flammable solvent. Replace the water as necessary, until the
water is no longer dirty. Dispose of the oil contaminated
water in accordance with your local by-laws.
